[0048] Such as figure 1 As shown, this protocol is divided into three stages: system initialization, pre-processing of data packets, and data packet verification, as follows:
[0049] The first stage: the system initialization stage, the base station generates a one-way key chain, and adds the key chain commitment value to the sensor node before the deployment of each sensor node;
[0050] The second stage: the pre-processing stage of the data packet, the base station uses the hash function to construct a legal data packet of a specific data item;
[0051] The third stage: the data packet verification stage, the sensor node verifies the received data packet, if the received data packet is a legal data packet, then accept the data packet and update the sensor node, otherwise directly discard the data packet .
[0052] During the system initialization phase, such as figure 2 As shown, the base station picks a random number K b , and then generate a one-way key chain, by K ...
